Chapter 5: Operation
5.1 Types of Power Supply
The light source can be either battery-powered or AC adaptor-powered, giving total flexibility
for most testing sites and situations.
5.1.1 AA battery
When using AA battery, will display on the left top of the screen (fig.5-1)
Battery Power indicator
5-1
There are five grades of battery power indication:
70%-100% power
40%-70% power
30%-40% power
20%-30% power
Less than 20%, the power meter will shut down.
Replace batteries. Refer to below figure 5-2
5-2
Push the clip fastener on the battery compartment cover down. Remove the battery compartment
cover and remove all three batteries, making a note of their positive and negative orientation. The
negative battery connector should be against the spring. Insert 3 new 1.5VV AA batteries. Refit the
battery compartment cover. The clip fastener should click shut.

source to laser on its matched power meter. Hold down for few seconds. Light
source will enter Wave ID mode. “--AU” will be shown on the upper right of the LCD screen.
Enable power meter under “Wave ID” operation mode: Hold down for few
seconds. Power meter will enter Wave ID mode. “--AU”will be shown on the upper
right of the LCD screen.
Once the ID information is changed on light source (press to change wavelength),
after 3 to
5 seconds the detected information on the optical power meter will automatically
update to match. Refer to figure 5-14.
